Game used to ship with save files for each of the routes; bad, corrupt and good. You could change course on a couple of them I think, but I never updated the walkthrough due to two things (i) Dev's were editing/adding to the side events and (ii) I found it really easy to stay on 'course'.
Guess I'm an oddity on the last point!
My game have no such files. Surprisingly my last saves appear despite me having erase the game completely last time.
I have no problems startingover since it has been months since i played last.
My problem is, i like my Nat wild, but i sometimes mix bad Nat decisions with good ones i´m sure.
I will try to avoid the currupt path, didn´t like for her to be a murder just for the sake of it
